Question

more like you need a test cross. just by looking at the guinea - pig you would be able to tell if its genotype were hh or hh. multiple - choice question true false rewatch

Explanation:

In genetics, for a dominant - recessive trait, an organism with a dominant phenotype could have either a homozygous dominant (HH) or heterozygous (Hh) genotype. Just observing the phenotype (appearance) of a guinea - pig is not sufficient to determine if its genotype is HH or Hh. A test cross (breeding with a homozygous recessive individual) is often needed to determine the unknown genotype.

Answer:

False
